Watch: Errol Morris Revisits the Man Obsessed with the JFK Assassination Zapruder Footage in New New York Times Op Doc

In conjunction with the 50th anniversary of the JFK assassination in Dallas on November 22, 1963, Errol Morris has released to the New York Times another Op-Doc, called “November 22, 1963,” about the photographic evidence that exists of that fateful event.

After the great success his 2011 Op-Doc “The Umbrella Man,” which investigated a figure in the famed Zapruder footage whose identity is unknown (and whose use of an umbrella on a sunny day is incredibly suspicious), Morris interviews again Josiah “Tink” Thompson, a former philosophy professor who became wrapped up in spending time with the evidence from the assassination.

In the new Op-Doc, Thompson explains how the photos and film footage were collected, and how they were used to look for evidence throughout history, culminating in an examination of the frame of the Zapruder footage that has so enraptured him all these fifty years, frame #313.
